Agent Skills: code-auditor

Independent pre-merge review of a git diff, PR, or named files. Use when the user asks to review a PR, inspect current git changes, or hunt functional regressions, missed scenarios, wrong assumptions, concurrency bugs, and test gaps as an independent reviewer who does not defend the author's approach / 独立审查、功能回归、遗漏场景、错误假设、并发、测试盲区. Also use for a full-spectrum multi-dimension project audit across correctness, security, performance, readability, testing, and architecture / 全维度代码审计 / 全维度的代码审计. Not for maintainability-only or structure/refactoring reviews; not for applying code changes; not for repository health reports spanning compliance, privacy, cost, or accessibility. Do not modify product code. Output follows the discussion language.
